First Flight

The prototype flew for the first time in decembre 1988 at RAE Bedford, in the hands of Cranfield test pilot Angus McVitie.CMC has limited the aircraft to 130kt and a maximum altitude of 3,500ft. The Leopard prototype was tested from speeds as low as 75kt with maximum 41° flap.Minimum zero-flap speed was less than 90kt. Undercarriage cycling was proved during this flight.

Two-spar structure, primarily of GFRP, with some carbonfibre reinforcement. Full span electrically actuated trailing-edge flaps of carbonfibre, with deflections of +/- 45° for high drag landing and air-braking/lift dumping. No ailerons or spoilers.

Production aircraft was planned with liquid de-icing and decontamination system in leading-edge.
